IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 164,006, dated June 1,1875; application filed March 20, 1875.

To all whom it may concern Be it known that I, ABRAHAM KIMBER, ofMuncie, in the county of Delaware and State of Indiana, have invented anew and valuable Improvement in Lamp -Burners; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical section of mylamp-burner, and Fig. 2 is a plan view of the same. Fig. 3 is a verticalsectional view of my burner attached to a lamp.

This invention has relation to lamp-burners which are especiallydesigned for burning what are denominated heavy hydrocarbon oils, suchas crude petroleum and the like; and the nature of my invention consistsin a lamp-burnerhaving a perforated base, in combination with air-tubes,and with orifices in the sides of the burner above the base, and anair-gatherer, whereby currents of air are caused to circulate in thelamp-bowl, where they become charged with the vapor of the oil therein,and are then directed into the flame, as will be hereinafter more fullyexplained.

In the annexed drawings, A designates the body of my improved burner,which is externally screw-threaded, for the purpose of securing it tothe collar of a lamp-bowl, and which is hollow, as shown in Figs. 1 and3. The bottom a of the body A is thickly perforated, for the purpose offorming a communication between the interior of the lamp-bowl and theexternal air. The sides of the body A are also perforated, as indicatedat b, for the entrance of air-currents. B designates the wick-tube,which passes through the top and bottom of the body A; and O O areoblong tubes, which taper upward, and which are arranged on oppositesides of the wicktube. These tubes 0 O communicate with the interior ofthe body of the burner, and are for the purpose of. directing currentsof air and gas into the flame. D designates an annular concavo-convexskirting, which surrounds the body A, and is attached permanently to itabove the perforations b. This skirting D extends well over the upperportion of the lampbody, and when it becomes warm it will gather largequantities of air, and induce this air to pass into the body of theburner through the perforations b. Part of the air which enters the bodyof the burner will descend into the body of the lamp through theperforated bottom a, and by mixing with the vapors therein willbecomecarbureted, and then rise through the tubes 0 O and impinge on the sidesof the flame, thus facilitating the combustion, and enabling me tosuccessfully burn the heavy or crude oils without smoke or smell, andwith-. out any danger of explosion. The cone E and the chimney-gallery Fmay be constructed in the usual well-known manner. If desired, theinterior of the body A may have a partition in it, so arranged thatthere will be descending currents on one side of it and ascendingcurrents on the opposite side of it, thus dividing the circulation, sothat the currents will not interfere with one another.

What I claim as new, and desire to secure by Letters Patent, is-

In a lamp-burner for crude petroleum, having perforations a in itsbottom and I; through its sides, tubes G 0, leading to the upper end ofthe'wick-tube B, and annular skirting D, combined substantially asdescribed, and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
